    That's a cool process. Apparently a quarter has been replaced and the firewall altered. It must be awesome to have the body that clean in that short of time. I'd be rinsing the seams for a long time and blowing them dry with clean air.

    Pretty sure this is a board members car being restored by Nick Serwo at the present time. It should be back in the Nick’s shop sometime next week.

    Did it to a bunch of my sheet metal in the mid '80s. The most important thing is prepping everything properly for lots of epoxy primer, especially in spot welded seams, because the chemical strips from everywhere.

    Oh, and don't leave anything aluminum inside your doors, because it won't be there when you get the doors back! :eek: That was some pretty caustic stuff back then, it might be a bit more friendly to non ferrous metals these days.

    Just watching the video makes me remember the awful odors at Flint Paint Stripping LOL!

    Looks like it was originally a non AC car and the firewall was altered to install factory AC

    Never had one dipped. Stripped everything by hand. Always heard the horror stories about the un-neutralized stripper seeping out of the seams and ruining the final paint. Probably a case of "you get what you pay for".

    My Friends car. I found the video accidentally and jokingly asked him if it was his because I knew he was scheduled for the dip. I was surprised when he said yes. Then I thought how many 70, QQ, 4spd, GSX's are getting dipped this month, Duh! Is that firewall from someone possibly doing heater core surgery in the past?

    It had been converted at one point, and will be re-converted back to factory when restored.

    I have a GTO that had the doors, hood and trunk lid dipped in the 80’s by the previous owner. He wanted to do the body but luckily it was too big to fit into the tank. Every dipped panel has some seeping around the seams that look like rust stains. I’m sure the technology and processes are better these days.

    I was waiting to drop off a few small parts at a chemical stripping facility and saw a a couple of raggedy front fenders that were hanging on a rack. I asked the worker what was deal with them as they looked like the had been hanging there for awhile. He said that they were for a 60 something Ford. When they dipped the parts, the lower section disappeared! The guy that owned the fenders thought he had a solid part....but not so much!!
    I guess he refused to pay for them and there they sat.
    I've done suspension pieces and a few small parts, but after seeing what happened to those fenders, I hesitated to dip any body parts. I would want to be sure you have a solid part as a starting point!

    I had a car blasted. Stripped the trim and bumpers, drove it to the blasting facility and drove it the the paint guy. I left the light bulbs on it and zip tied the plates on. It was sweet to see how solid the body was - car was out of Georgia. No worries about chemicals leeching out. I'm sure Nick will know how to prevent that!

    I’ll post a proper thread once we get rolling at Nick’s.

    Dipped my X years ago and had an unusual outcome. The stronger trunk rods for the spoiler lost their torsion strength due to the chemicals and were ruined. Had to find another set, which wasn’t easy.

    Interesting - Was there corrosion on the rods?
